Can't remember, but I read that on one of the main sites sometime around when they were announcing the last quarterly info. Makes sense too. They announced that they are doing 4 devices in 2015, Classic and leap are already out. Only 2 left to come out, they announced the slider and another qwerty device before the end of the year. They already teased us with the prototype slider, so it will be the next one out as there is no info about the other qwerty. I doubt they would gear up to build and produce 2 phones to come out at the same time (unless samsung is building the slider), so i'm thinking slider late summer early fall then other qwert in dec.

There's a blacked out strip slightly covering the phone-search-camera buttons. Looks like it's the part where it would show the page numbers. The camera icon looks slightly different or could be the reflection.
